Yabachiba (ヤバチバ) is NET’s smart-pachislot AT machine built around direct bonus draws, cherry-count protection, bell-concentration states and the premium Rainbow 7 loop. The machine combines several bonus-entry routes rather than a conventional CZ-to-AT progression.

Setting probabilities and payout rate
Setting probabilities and payout rate
Administrator research. The reliably published setting-wide comparison is the payout rate. Current Setting 1 references place overall bonus initial hits around 1/398 and Rainbow 7 initial hits around 1/5716; corresponding complete figures for higher settings are not published consistently enough to interpolate.
| Setting | Payout rate |
|---|---|
| 1 | 97.1% |
| 2 | 98.3% |
| 4 | 102.9% |
| 5 | 105.1% |
| 6 | 110.1% |
Setting L is a special non-play setting with a distinctive panel behavior and should not be treated as a normal selectable performance setting.
Small-role probabilities
Small-role probabilities
The small-role table describes appearance frequency. The chance to clear a feature after drawing a role is a separate conditional probability.
Administrator research. Additional play and result interpretation:
| Role | Setting-1 appearance reference |
|---|---|
| Push-order bell, 15 coins | 1/1.3 |
| Replay | 1/7.3 |
| One-coin role | 1/3.7 |
| Common bell, 3 coins | 1/27.5 |
| Watermelon | 1/79.7 |
The 15-coin push-order flag is not a promise that an un-navigated normal-play spin retains fifteen coins. Follow displayed navigation in the applicable state. These appearance references are also separate from the cherry-count ceiling: the ceiling counts actual eligible cherries, not the bell or replay frequency.
Game flow
Game flow
Normal play uses several direct bonus routes: an every-game draw, cherry-based draws, a cherry-count route, bell-concentration behavior and lamp-based bonus cues. The machine therefore does not depend on a single CZ gate before its main payout states.
Premium progression can enter Rainbow 7 Mode. Its mini-hanagasa display can light progressively, and a completed pattern shifts the loop toward Rainbow 7 bonuses.
Administrator research. Additional play and result interpretation:
Three routes can create a bonus chain
- Normal play draws bonus stock through eligible cherries, setting-change behavior and the 100G-after-bonus draw. The cherry counter is a separate protection mechanism.
- After a bonus, stored stock can announce within 32G. A loop draw and a 1G-chain stock are separate contributors, so a quick sequence need not identify which route won.
- The small Hanagasa lamp collects one level after REG and two after BIG. A bonus within 100G carries the level forward; reaching level ten leads to Rainbow Seven.
- Bell Concentration (ベル集中) is a temporary coin-building state. Its game counter and net increase describe that state rather than a fixed normal-game bonus ceiling.
Ceiling, reset and quit timing
Ceiling, reset and quit timing
Administrator research. Bonus protection applies at 999G + α without a bonus or on the 40th cherry. After a setting change, the cherry-count ceiling is shortened from 40 to 30. Both routes award a bonus rather than a separate AT-interval reward.
Stored bonus stock is normally released within 32G, so 32G after a bonus is the basic review point. If mini-hanagasa lamps remain lit, following to around 100G may retain value because those lamps can carry through the 100G range.
Administrator research. Additional play and result interpretation:
The 40-cherry protection, shortened to 30 cherries on setting change, counts cherry results rather than elapsed games. Bell Concentration changes coin retention and play duration as well. A fixed maximum yen amount cannot therefore be derived by substituting 40 into a game-count cash formula. Check for confirmed stock, the 32G announcement route and relevant lamp levels before applying a basic stopping decision.
Bonus, Bell Concentration and Rainbow 7
Bonus, Bell Concentration and Rainbow 7
Ordinary bonuses run at approximately 6.0 coins/G net increase in current analysis. Bell Concentration is a separate accelerated state at approximately 1.8 coins/G.
Rainbow 7 Mode upgrades the premium loop. Rainbow 7 Bonus begins with a 777-coin allocation plus α and runs at approximately 6.0 coins/G, with a 1G loop draw after the bonus.
Administrator research. Additional play and result interpretation:
| Bonus / state | Published payout / duration | What the number describes |
|---|---|---|
| BIG (ビッグ) | Approx. 110 coins; approx. 6 coins/G | Coins won in the ordinary BIG; not a 110G duration |
| REG (レギュラー) | Approx. 50 coins; approx. 6 coins/G | Coins won in the ordinary REG; not a 50G duration |
| Rainbow Seven (虹7) | Approx. 777 coins + α | Premium bonus with its own 1G-loop route |
| Bell Concentration (ベル集中) | 200–400G; approx. 1.8 coins/G | Temporary bell state |
The initial bonus is approximately a 1:1 BIG/REG split. The approximately 67.2% overall chain expectation combines its ordinary chain routes; Rainbow Seven has a separate approximately 77% loop. Do not add the two percentages or apply Rainbow’s loop to every REG.
AT-system behavior
AT-system behavior
Yabachiba’s AT-style payout structure is expressed primarily through bonus and concentration states rather than a conventional named continuous AT with a single entry probability. The key progression elements are Bell Concentration, bonus stock and Rainbow 7 Mode.
Setting differences and identification
Setting differences and identification
The published payout-rate spread is the dependable setting-wide numerical comparison. Because complete setting-by-setting bonus initial-hit values are not currently published consistently, do not infer missing rates from the Setting 1 reference. Setting L is identifiable by its special panel behavior and is not part of ordinary play evaluation.
Modes and internal states
Modes and internal states
Administrator research. Additional play and result interpretation:
Stock, lamp levels and cherry count measure different things
The published ordinary cherry stock draws are approximately 0.01% for weak cherry and 48.9% for strong cherry. Setting-change stock expectation is approximately 75%, while the eligible post-bonus 100G draw is approximately 42%. The weak- and strong-cherry stock draws apply only when that cherry does not win a bonus, and a successful draw awards one continuation stock. These are conditional on their own triggers, not per-normal-game bonus probabilities.
Cherry vibration describes the bonus-winning draw, not the separate continuation-stock draw. The strongest vibration indicates a bonus for either weak or strong cherry; weaker patterns have lower bonus-winning rates. The published vibration rates include wins at the cherry-count ceiling. Record the cherry and vibration together.
Setting hints and confirmed-setting elements
Setting hints and confirmed-setting elements
Administrator research. Additional setting hints and result interpretation:
Reading the stock cue without calling it a setting cue
| Stock cue colour | Published implication |
|---|---|
| Yellow | At least one stock |
| Green | At least one; stronger expectation of two |
| Red | At least two stocks |
| Blue | At least three stocks |
| Rainbow | Continuation stock until Rainbow Seven Mode is reached |
The stock colours above are shown by the reel backlight when the SP button is pressed after the initial bonus alignment. On the separate top lamp at bonus end, green indicates next-bonus continuation, red indicates a next BIG or better and rainbow indicates a next Rainbow Seven bonus. These stock / bonus implications do not establish a high machine setting.
How to play
How to play
No navigation: stop the left reel first. If numbered stop instructions appear, press the stop buttons in the displayed order (1, then 2, then 3). A symbol-target instruction tells you which symbol to aim for; follow it together with any displayed stop order.
Use left-first play when no navigation is shown. Aim BAR on the left reel; the machine’s BAR/black-7 guide points allow normal small-role coverage while following the displayed stop-order instructions. Do not deliberately use middle-first or reverse-order play during unassisted normal play.
During bonuses and instructed states, follow every push-order/navigation prompt.
